Fix the roll mess in transform. Since roll is based on an automatically calculated up axis, transforming bones would mess up bone orientation. This code automatically adjusts the roll value to keep bone orientation as consistant as possible. That works all around in transform for all transformations.
Doesn't work with x-axis mirror though as that doesn't use transform elements (fixing it would be nice for later)
Most interesting is that it works with the mirror tool (obviously), so you don't have to fix all the rolls after mirroring one side of an armature.
It could be made an option if someone presents a good enough point for that, but I can't see why you'd want the previous mess instead.
NB: this also ports a utility fonction from etch-a-ton to set bone roll from an up axis.

This patch adds the CTRL-ALT-A hotkey to align bones in armature edit mode.
It works the same way as parenting: selected bones will be aligned with active bone, if only one bone is selected it
will be aligned with its parent (if any)
Thanks!
|
|
Will have to do a second pass tomorrow to fix some leftovers.

Can now also convert active layer to a series of bone chains. Each stroke will be converted to a chain of connected bones.
At the moment, it is still necessary to manually recalculate roll angles after the armature has been created, as the bones are not assigned the correct roll angles yet.
|
|
In PoseMode, the Ctrl-A hotkey can now be used to apply the current pose as the new restpose for the armature.
Notes:
* Roll correction may not be totally correct on bone chains, but is ok in most cases.
* Objects that are bone parented to the armature where this is applied are not correctly adjusted yet.
* It is advisable to 'apply' the existing armature deformations to geometry deformed by the armature before applying this, to prevent unexpected results.
* No menu entry yet... will add in due course.

they now use a macro I introduced in the previous commit.

* New Tool: Switch Direction
This tool switches the direction of selected bones in EditMode, and can be found under the Specials Menu (WKey). It also adjusts the parenting, so that continuous chains can still be linked.
* Bone Locking:
Removed Lock/Unlock functions from Specials menu, and moved this functionality under the Toggle/Set/Clear Bone Settings tools (Shift/Ctrl-Shift/Alt W respectively)

These are for use in pose mode or armature edit mode, to let you quickly traverse up and down a chain of bones.
It's quite useful for bones that are in hard-to-click places.
The tools are:
*Select parent/child ( [ and ] )
selects the parent or child of the active bone, deselecting the original active bone
* Extend select parent/child (shift [ and shift ] )
selects the parent or child of the active bone, adding to the selection
Thanks to Joshua for reviewing this so promptly!
PS. I'd like to use these [ and ] keys more widely in blender as consistent 'select next / previous' tools. I can imagine it being very useful for a lot of things like keyframes, nodes, mesh edges, etc.

This patch adds the ability to lock transformation on bones in edit mode, to protect them from accidental editing.
Bones can be locked from the editing buttons, the transform property panel, the specials popup menu or the python api.

Initial commit of Separate tool for Armatures. Currently, the functionality is hidden behind a temporary patch, as there are still issues to be worked out (crashes under certain conditions and a re-linking issue). It may remain like this for the release if I can't get it to work correctly.
Note:
- Hotkey for separate is Ctrl-Shift-P (it's a bit clumsy, and isn't consistent with P for separate for meshes, but Select Parent(s) is better as P)
|
|
quick-toggle tools, bones now have this functionality too.
Use Shift-W to toggle, Ctrl-Shift-W to enable, and Alt-W to disable one of the bone's settings.
|
|
Added three new tools to the WKEY menu for Armatures in EditMode/PoseMode. These add .* extensions to the names of selected bones based on their position in 3d-space on the axis considered by that tool.
The current naming schemes are based upon the extensions I normally apply. Some people may have slightly different preferences though.
There is one for:
* Left-Right names (along x-axis)
* Front-Back names (along y-axis)
* Top-Bottom names (along z-axis)
|
|
This commit introduces two (currently only one is actually functional) new features for working with armatures.
* Bone Merging (Alt-M)
It is now possible to select a bunch of linked bones and "merge" them together. Currently, there's only one option to merge bones that are selected and linked to each other in a chain.
* Add Bone Between Joints (FKEY)
This allows you to select a few joints, and have a bone created between them. Currently, this is not yet functional (but the code is there)

This code adds a basic and simple skeleton generator.
Examples and links are in the wiki, docs will come eventually: http://wiki.blender.org/index.php/User:Theeth/skeletor
In a nutshell, select a vertex at the top of the head and press "Generate Skeleton". UI Panel is in the Editing buttons in Edit Mode, tooltips and semi-useful.

This is very much a work in progress commit to allow me to work outside of home.
While it does somewhat work, I wouldn't recommend anyone to use it.

This patch, by Juho Vepsalainen (BeBraw), introduces subdivide multi functionality for armatures. It lets you specify the number of divisions that selected bones should be divided into.
I've slightly optimised the code a bit, though the change shouldn't make much of a difference. I've also fixed a minor bug in the menu highlighting, due to duplicate menu event-codes.

Brecht's cool heat-skinning stuff.

In this commit, a new way to set the bone roll is introduced. It aligns the z-axis of the selected bone(s) to the 3D-Cursor, so that the cursor intersects with the YZ plane.
This makes it easier to align bone rolls to a target, for use in rigs where arms/legs are not horizontal/vertical. To use this, just press Ctrl N, and choose the "Align Z-Axis to 3D-Cursor" option.
Credits go to Robert Christian (wavez) for providing the method as a working BPy script, that demonstrated this in action.

Armature undo was incomplete; no less then 6 places needed undo pushes.
Added undo pushes, and made sure deselectall_armature/posearmature played nice
and only did undo pushes when they're called with AKEY.
This seems like a fairly old issue. I guess people just didn't notice it enough
to file a bug report. :)

Since 2.40 (and a few pre-releases around then), armature joining has not
worked correctly. Constraints and other attributes of bones in posemode
(IK DOF limits, transform locks, custom shapes, etc.) were not preserved
on the armature(s) that were joined onto the last selected armature. This
was a serious production problem, as it meant that you could not easily
add pre-made rig segments and merge them with the rest of your rigs without
having to redo all the constraints. After a few attempts, I've finally
managed to fix this.
All constraints and parenting relationships get name corrections for the post-
merge armatures. Action channels in actions don't really get any corrections
yet unless the action is being used by an Action Constraint.
Python-API people: beware, I may have broken something in this commit.

After all these years, it is now possible to (re)center armatures like you
can do with meshes and curves.
At the moment, you can only access this functionality from the menus
(Spacebar->Transform) as the armature button panels are pretty
crowded.

bone drawing on/off. Is default on.
|
|
(Merging is *not* fun work, especially not with bugfixes in main branch
for code that got cleaned up in the other! Poor Hos... :)
|
|
eg.
ret_val = ob.join(objects)
Now it dosent depend on the current selection, or change the selection context.
Made respective join_* functions return 0 if the join was not mode, 1 when it workes.

Works like for Object layers, but local within Armature itself. Each Bone
can be in (16 now) any layer, and the Armature layer defines what is
visible or not. Also note that hiding will still work too.
Since the Blender code is *stuffed* with Bone options now, this commit
requires a good test if all tools we got now comply to layers...
(I counted 130 cases for checking for selected Bones in code!)
In PoseMode; hotkey M will show 'movetolayer' menu. Not in editmode...
then its the mirror menu.
Todo: make action/nla drawing comply to Armature layer settings.

This commit is based on the patch & cool design work of Matt. It includes
the new Lamp drawing style, and replaces the Object center dots with a
similar styled OpenGL drawn dot.
Important side-note is that removing the old glDrawPixels() for centers or
lamps will not only make Blender faster, but also prevents crashing on a
couple of cheaper 3d cards (as reported for S3 and Intel on-board cards)
Notes:
- The new default only draws Object centers when selected or active. If
you like to see them always, use the View Properties Panel. You can also
save that in the .B.blend
- The size for centers (and lamps) is in the User settings "View & Controls"
- Unselected Lamps, and their offset lines from zero Z, are drawn in a new
Theme color
Changes and additions in Matt's patch:
- Lamps and centers are drawn fixed size, in pixels. Also the 'sun' lamp
draws screen aligned now.
- Center dots now also draw in blue to denote Library linkage or to show
that an Object has been linked to other scenes.
- When objects are empty (no vertices) they will always draw a center dot.
Otherwise these objects would never be selectable anymore!
- Added theme setting for center size, and initialization
- Removed the old redundant code for drawing centers
- Cleanup of drawing routines, made center dots faster
- Started removing calls to glBlendFunc(). Regular alpha drawing should
become standard, and the (very) occasional exception should return this
to default after usage.

- Action Editor: hotkeys V and H for handles were invisible, added menus
- NLA strips: when current frame is exactly on the strip end, it didn't
include that action... needs a rounding correction for it.
- Action/NLA: deleting keys in Action, which results in only 1 key left,
resulted in zero sized strip length. Now the strips are defaulted to be
1 frame in size minimal.
- NLA editor: ALT+C "Convert to strip" didn't increment Action user count
- 3D Window: CTRL+P make parent to Bone still gave the insane menu with all
bone names. With unified PoseMode select it can just parent to the
active Bone. Note; this now requires the Armature to be in PoseMode to
work.
- Rotation Constraint; the new options to only map to X,Y,Z rotation, did
set the not mapped rotation axes to zero. These should remain unchanged.
- AutoKey optionn for Actions; should not insert action keys on ESC
And added a fix myself:
- When SHIFT+selecting a Bone in PoseMode, and the Armature was not selected
or active yet, it doesn't extend-select/deselect the Bone anymore.
This case is only useful when you try to add IK or Constraint, so the
shift+selection should only activate the clicked Bone.
|

- Added (BKE_utildefines.h) POINTER_TO_INT(poin) and INT_TO_POINTER(int)
defines, to help fixing issues with switch to 64 bits systems. This
assumes that a) not more than 16GB mem is used and b) that address
space is below the 1<<35 value. The latter has to be confirmed, but it
seems to conform the current 64 bits generation of OSs (for mallocs).
Needless to say; use long if you want to store pointers! This is for
temporal fixing.
- Added editmesh version for mesh-octree lookups, not used yet.
- Fix: ESC on armature posemode restored the actions, should not happen
- Fix: If in NLA an action was 0 frame long, it caused draw error
- Fix: Click on name in Action Window now activates Bones
- Fix: "Snap to" options in Armature editmode now use X-axis mirror edit.

Using "make parent armature with creating vertex groups" option gave
corrupted memory when one or more bones had the "Deform" option not set.
Was caused by old boneclass SKINNABLE variable. To end this confusement,
removed this define from code.
Note for future Armature tool coders; don't use this bonelooper
functionality. Operations in Object mode for armatures should use the
Pose Channels, which is a simple ListBase to go over. I have to recode
the 'create vertexgroups' still...
|

yet. Need commit so I can access it on the compu in Orange studio :)
|
|
- Removed old convention that only allowed one "IK" connection for Bones
in a joint. Was highly frustrating for editing trees or branches.
In a next commit, there will be a different method to define IK target
and IK root, so this option actually will become "Connect Bone" or so.
- the IK group name is gone, now is just an option "Tree IK". When IK
chains share a root they'll form a tree.
Todo is preventing conflicts here (will be for editor to define IK Root)
- Adding new IK constraint with CTRL+I activates Constraint
|
|
For defining the deformation distances of Bones, three values are being
used now. The bone tip and root radius define the bone-shape itself and the
"dist" defines the soft area around it. A full (user) doc is in CMS here;
http://www.blender3d.org/cms/Armature_Envelopes.647.0.html
Note: todo still is allowing both Vertex Deform Groups and these Envelopes
together (and or per Bone).
Also part of this commit is:
- New: Hiding bones in EditMode. This is a separate 'hide flag', so you can
keep the PoseMode hidden Bones separate from EditMode.
(In the future we should do some kind of bone-grouping or so)
- While transform(), the hotkeys G,R,S only switch mode when the previous
mode was compatible. Caused conflicts with Crease/BoneDist/etc.
- Deleting the last VertexGroup now also deletes the entire Mesh 'dvert'
data. Sounds logical, but remember that VertexGroups are partial on a
Mesh, partial on Object. Weird design decision though...
Anyhoo, at this moment the only way to have Bone Envelopes deform, is
by deleting all VertexGroups!
- In PoseMode, the hotkey ALT+S now does both B-Bone size or Envelope,
depending draw type.
- In EditMode, Extrude now also works when only Root points were selected.
- Weight editing is also symmetrical btw, with the "X-axis Mirror" option
set.
|
|
In WeightPaint mode, pose-mode armatures now allow selecting Bones, but
without making the Armature object active.
Selecting a Bone then results in selecting the associated vertexgroup. :)
Little quirk; all armatures with posemode then draw selectable...
|
|
- Option is in EditButtons, Armature panel.
- Currently only local X-axis mirror (seems to be default anyway)
- Transform then applies changes to the mirrored-name bone as well.
- Extrude: also does the counterpart Bone
- New: SHIFT+E extrude: extrudes 2 mirrored Bones out of a normal Bone.
(creating names by appening _L and _R)
Or in short: you can now model a full rig without any manual naming!
Of course the names are not too nice... a couple of ideas to explore;
- rename a mirrored bone renames counterpart too
- allow in weightpaint mode to select Bones
- and of course mirrored edit in PoseMode (if that's useful...)
Important note: I tweaked the naming convention a bit; names like
Bone_L.005 and Bone_R.005 are considered counterparts. However, if
you use the "Flip names" option, the number extension is still
truncated.
BTW: Commits in Zr's code are fixes for gcc warnings. :)
|

(And moved flip_name to armature kernel)
|

- PoseMode now is a state Armature Objects can be in. So, while in PoseMode
for an Armature, you can just select another Object or Armature.
- The old PoseMode options (transform, insert keys etc) are accessible
with making the Armature Object 'active' (and have object in PoseMode).
- At this moment no multiple Poses can be transformed/edited at the same
time.
- The old hotkey CTRL+TAB, and view3d header menu, still work to set an
Object's PoseMode
It was quite a lot recode, so tests & reports are welcome.
Oh, as a bonus I added Lasso Select for Bones in PoseMode! It selects using
only the line between root and tip of the Bone.
|
|
- Add Armature or Bone (SHIFT+A) now adds by default a single Bone, view
aligned and of unit-size 1.
- Then use E-key (extrude) to draw chains, this option now doesn't popup
the "OK" requester anymore, so works fast
- Another new method is using CTRL+click to add Bones
This makes it working identical to the other edit modes in Blender. The old
modal loop for drawing bones just wasn't working well either.
Related to this; have a real set of useful Armature primitives?
2) Removed event REMAKEALLIPO, which was added in NaN days for testing, and
proved to be extremely slow. Code is moved now to editnla.c.
Thanks Tom Hendrick to pointing to this nasty buggy feature!

The B-Bones!
(where the B can be read as 'block' or 'bezier' or 'b-spline')
- set option on/off in edit buttons, armature panel
- scaling of B-bones only works in editmode, use ALT+S to make bones fatter
or thinner. Also works for constrainted transform
- In pose mode, you now have a buttons panel with per-bone settings too
Here you can find the "segments" button, which allows bones to
interpolate between previous/next bones, including roll.
- Buttons to control interpolation ("In" and "Out" are disabled, doesn't
work satisfying yet
NOTE: this doesn't give deform yet! Main purpose for now is to test if this
drawing method serves to animate/pose armatures well.
Still need to review proper interpolation methods... maybe bezier is too
limited.
|
|
- In Solid drawmode, bones get drawn solid too now. Including Outline-
selection color, if that's set.
Disable it by setting Object-buttons "drawtype" for the Armature.
Color used for solid bones is in Theme editor.
- EditMode armature now follows (Mesh edit) theme colors (Vertex, Edge)
- PoseMode armature has ThemeColor for selection, and draws three extra
colors now;
- blue shade for bones with action Ipos
- yellow for bones with IK
- green for bones with a constraint
- "X ray" now only works for PoseMode... needs review, can be done better
- "Draw Names" option uses theme color too, also indicates selection.
Fixes;
- In Armature EditMode, the deformed Mesh goes to rest-position
- Border select didn't clear 'active' flag in Bones in PoseMode
- Mouse-click select didn't work when a dashed line was close to Bone
